Abstract

The world population is ageing. In the aged society, grasping the body condition of the elderly is helpful to choose appropriate rehabilitation. This research focuses on the outdoor walking analysis by use of the simple foot mounted IMU system. The walking feature values are estimated by the algorithm, and they are combined with the GPS data obtained by smartphone to compare the feature values of frail elderly and healthy subject. The differences of walking feature values that are calculated by this system show the usefulness of developed system. The developed system is simple, but useful to grasp the gait features changing of the user.

基于简易足部IMU系统的户外行走步态特征监测
世界人口正在老龄化。在老龄化社会中,掌握老年人的身体状况有助于选择合适的康复治疗。本研究主要是利用简易足部IMU系统进行户外行走分析。通过算法估计行走特征值,并将其与智能手机获取的GPS数据相结合,比较体弱老年人和健康受试者的行走特征值。该系统计算的行走特征值的差异表明了所开发系统的实用性。该系统结构简单,但能有效地掌握使用者的步态特征变化。
